Number of total cells in the BALF and expression of the IL-6 mRNA in the mouse lung. Six- to eight-week-old male C57BL/6 J mice were exposed to CS for 6 months or CS for 6 months and an intranasal instillation of LPS on days 1 and 14. a Number of total cells in the BALF from mice sacrificed in the indicated month from the control group (n = 6), CS group (n = 6) and CS + LPS group (n = 6). b Relative IL-6 mRNA levels in the lungs of mice sacrificed in the indicated month from the control group (n = 6), CS group (n = 6) and CS + LPS group (n = 6). Data are presented as the means ± SD. #P < 0.05; ##P < 0.01 for the comparison of the CS group with the control group; *P < 0.05; **P < 0.01; ***P < 0.001 for the comparison of the CS + LPS group with the control group; &P < 0.05; &&P < 0.01 for the comparison of the CS + LPS the group with the CS group
